CHARLES L. MEYER AND NICHOLAS P. HICKEY, OF DETROIT, MICHIGAN, ASSICNORS TO THE COMMERCIAL GAS COMPANY, LIMITED, OE WIN DS OR, CANADA, A CORPORATION OF (AN- ADA.

a certain new and useful Improvement in Apparatus for Carbureting Air, and declare the following to be a full, clear, and exact description of the same, such as will enableothers skilled in the art to which it pertains to make and use the SEIIILQ IOfOIOIICG being had to the accompanying drawings, which form a part of this specification.

This invention relates to apparatus for earbureting air, and the object'of our improvements is to prov de an improved apparatus that shall charge-air with conibusti ble vapor.

In. the drawings :-Figure 1, is an elevation of the entire apparatus. Fig. 2,-is a central section of'the primary and'lsecondary carbureters. Fig. 3, is a plan view of a circular frame for holding sheets of wire netting and felt between said sheets. Fig. 4:, is a plan view showing the frame of Fig. 3' with the wire netting in place. Fig. 5, is a section on the line 5-5, Fig. 2. tional view of the upper part of the car bureter and of the rose 13.

A, represents an air compressor.

B, is a reservoir, and A is a pipe leading from the delivery ports of the ci'mipressor to the reservoir B.

I), is a pressure gage-on the reservoir.

C, the primary carburetor.

B, is a pipe leading from the reservoir B, to the carburetor (l, and terminating in arose B toward the upper end of said carbureter.

'7), is a cook in the pipe B.

l), is a secondary carburetcr shown, as secured to, and axially in line with, the primary carbureter C and below the latter.

c, indicates circular or annular l ranics adapted to support sheets of wire netting inclosii-lg sheets oi felling between them. These frames, with attached parts, l'orin diaphragms and .l) in .the carburetors C and l).

fluid.

B is a pipe communicating with a pipe B, and with the reservoir E.

b, is a! rock in the pipe B Specification of Letteirs Patent. Application filed. August 13, 1906. Serial No. 330,366.

Fig] (3, is a detail secl), is a reservoir for a volatile combustible AI?JEAILK'JYU'S FOR CARBURETING AIR.

e is a screw plug stopping the hole throu h which the hydrocarbon forming the COmbR S- tible material may be introduced into I the reservoir E.

the rose B Batented March 10, 1908.

The rose B is in the. form of a double walled hollow cone with its opening downward, and its lower wall is pierced with a large number of small apertures;

D is a pipe leading from the lower end of the primary carburetor C to the lower end of the secondary carburetor D, and ending in a coil 1), having small apertures opening downward through its walls.

1), is a pipe having a cock therein through which the secondary carburetor D may be drained.

D is a pipe leading from the lower end of the reservoirE to the lower end of the secondary carbureter D.

d, is a cock in the pipe D d, is a glass gage by which the height of the fluid in the secondary carburetor D may be observed.

D, is a reservoir for hydrocarbon liquid having a screw plug d closing a supply opening therein.

D is a-pipe leading from the lower end of the reservoir D" to the lower end of'the secondary carburetor D, and having a cool: d

therei E is a pipe connecting .the top of the sectween the top of the secondary carbureter 1) and the. bottom of the reservoir F.

f, is a cock in the pipe F.

The operation of the above described device is as follows: Air is supplied to the reservoir B by the compressor A. The air pressure in the reservoir B is communicated to the reservoir E above tize fluid therein by the pipe B Air is permitted to pass through the pi e B into therose B? and is. ue in jets from t 1e small apertures in the lo er wall of fromthe reservoir E to the prinlilary oar; s t e jets 0 bureter C may be regulated. air and fluid 'are in opposite directions, the

jfiuid, is vaporized and the vapor well mixed with the air, but should any fluid escape without being vaporized, it falls upon t e pads of the diaphragms O and the air passing down through said diaphragms converts it thoroughly into va or.

The bottom of t e carbureter C is made slanting and-there are a series of fins orprojections C for breaking up and gasifying any liquid that might reach the bottom of the carbureter C.

Should any li uid still escape, it is carried to the bottom 0 the primary oarbureter C, and passes to the bottom of the secondary carbureter D. A body of gasolene or other carbureting fluid is kept in the bottom of the secondary carburetor D, being supplied thereto as required from the reservoir -D through the pipe D, and its supplyregulated by the cock (1. The air and vapor from the primary car-bureter C pass downward through. the pipe D and into the coil 1), and flows outward and downward through the apertures in the lower portions of the wall of the coil D, and bubbles up through the body of hydrocarbon d" in the secondary reservoir D, and passes through the diaphragms D which are entirely similar to the diaphragms C tothe top of the carbureter D, and from thence it passes through the pipe F at the rate controlled by the cockf into the reservoir F. The relative pressure in the primary carbureter C and the second ary' carbureter I) may be adjusted by the pipe E and e diaphragms I), so that they remain dry and the gas passing upward through them is a perfectly dry and fixed gas.

By adjusting the relative ressures in the reservoir E and carbureter fluid may be pJaSsed in either direction through the pi e and its amount and rate of flow may be regulated by the cock d The pipe E may form a by-pass by which No liquid ever falls on the the secondary carbureter D may be entirely out out.

r M, N, O, are fixed pulleys and P, is a cord secured at one end to the movable portion of the gasometcr l and passing over -iulleys M, N, O, and downward and over wheels on the stems of the cocks b and e, so that a move ment of the gasonieter will turn said cocks to regulate the rate of workin of the apparatus.

An aluminium float is placed in the reservoir E to separate the fluid from the air above it.

v What we claim is 1. In an apparatus of the kind described, a carbureter casing, an inlet for air provided with abroad rose at its end, a pi )e for the induction of liquid fuel, said pipe eing shaped into spirals within said casing, the spirals being formed into surfaces parallel with the foraminous surface of the rose and adjacent thereto, and provided with apertures opening toward said rose.

2. In an apparatus of the 'kind described, a carbureten casing, an induction ipe for air having a rose at its end having its oraminous surface in the sha e of a cone, an induction pipe for liquid fue formed into spirals within the casing, said spirals being arranged adj acent to the foraminous surface of the rose and arranged in a surface parallel to such surface, for the purpose described.

3. In a carbureter, the combination of means for delivering air in one direction in small streams extending over a considerable area, and an ap aratus for delivering carbureting fluid in t e opposite direction to and against the incoming air in a finely divided condition and over an approximately equal area to that over which the incoming air is distributed, said areas being located adja cent, and opposite, to each other.

4. In a carbureter, the combination of a delivery passage for air, a rose at the end of said delivery passage, and means adapted to deliver carbureting fluid in a divided condition in the opposite direction to that of the air flowing from said rose and over an area approximately equal to that of said rose, said rose and means for delivering the fluid being located adjacent, and opposite, to each other.

In testimony whereof we sign this specification in the presence of two witnesses.
